Was the whole lot out of the same car or different parts put together?

If the BCM and ECU aren't linked and the keyhead isn't linked to the BCM it will crank and not start. Easiest thing to do is take the ECU to a tuner and get them to turn VATS off. Otherwise a Tech 2 is required to link everything.
